Herein, the control unit 21 may be an electronic component capable of completing coordination and command system work, such as a controller.
The control unit 21 is configured for storing a prestored first encryption algorithm and a prestored first key, and is further configured for carrying out the electronic cigarette control method to perform identity authentication for the atomizer 10 and the power device 20 and to control the operation state of the electronic cigarette according to the identity authentication result.
The power supply 22 may be a chemical power supply, for example, a dry cell, a lead-acid accumulator, a lithium-ion battery, etc.; when the atomizer 10 is connected to the power device 20, the power supply 22 is configured for supplying power to the atomizer 10, such that the atomizer 10 heats an atomization substrate to generate an aerosol.
The connection piece 23 is arranged at an end part of one end of the power device 20 for connecting to the atomizer 10; the connection piece 23 may be a component capable of realizing circuit conduction, such as a spring plunger, an elastic piece and a golden finger.
When the atomizer 10 is connected to the power device 20, the encryption authentication unit 11 is connected to the connection piece 23, such that the encryption authentication unit 11 is conducted to the power supply 22 and the control unit 21 through the connection piece 23; meanwhile, the power supply 22 can supply power to the encryption authentication unit 11, the encryption authentication unit 11 is in communication connection with the control unit 21 (as shown in FIG. 4), such that the control unit 21 can perform identity authentication using a second identity authentication code generated by the encryption authentication unit 11; the heating element 12 is connected to the power supply 22, and the control unit 21 controls the power output from the power supply 22 to the heating element 12, so as to control the heating condition of the heating element 12, that is, to control the operation state of the electronic cigarette, including controlling the electronic cigarette to activate and prohibiting the electronic cigarette to activate.
Herein, the encryption authentication unit 11 can perform wired communication connection or wireless communication connection with the control unit 21. The wired communication connection includes I2C bus, 1-Wie bus and the like; and the wireless the wired communication connection includes Bluetooth, 3G, 4G, WiFI and the like.
After the encryption authentication unit 11 is in communication connection with the control unit 21, the control unit 21 carries out the electronic cigarette control method, to perform identity authentication for the atomizer 10 and the power device 20 and control the operation state of the electronic cigarette according to the identity authentication result. Specifically:
the control unit 21 generates a first identity authentication code, and acquires a second identity authentication code from the encryption authentication unit 11, and then the control unit 21 performs identity authentication according to the first identity authentication code and the second identity authentication code, controls the electronic cigarette to activate if the identity authentication is passed, and prohibits the electronic cigarette to activate if the identity authentication is not passed.
Herein, the step of the control unit 21 generating a first identity authentication code specifically includes: the control unit 21 generates a random challenge data, and acquires prestored atomizer information from the encryption authentication unit 11, wherein the prestored atomizer information includes manufacturer information, version information, production information, a tobacco liquid type ,etc.; and then the control unit 21 performs a calculation on the random challenge data, the acquired prestored atomizer information and a prestored first key according to a prestored first encryption algorithm, to generate the first identity authentication code.
Meanwhile, the control unit 21 further sends the generated random challenge data to the encryption authentication unit 11, so that the encryption authentication unit 11 performs a calculation on the prestored atomizer information, a prestored second key and the received random challenge data according to a prestored second encryption algorithm, to generate the second identity authentication code; meanwhile, the second identity authentication code generated by the encryption authentication unit 11 is the second identity authentication code that the control unit 21 needs to acquire.
During the process of the encryption authentication unit 11 generating the second identity authentication code, the prestored atomizer information includes manufacturer information, version information, production information, a tobacco liquid type, etc.
Further, the prestored first encryption algorithm and the prestored second encryption algorithm are both secure Hash algorithms (SHA). Preferably, the first encryption algorithm and the second encryption algorithm are SHA-256.
The first identity authentication code and the second identity authentication code are information validation codes or MAC codes, which are both calculated based on the prestored atomizer information; therefore, the first identity authentication code and the second identity authentication code represent the identity of one same atomizer. The first identity authentication code is calculated at the power device 20 end through the prestored first key and the acquired prestored atomizer information, while the second identity authentication code is calculated at the atomizer 10 end through the prestored second key and the prestored atomizer information, that is to say, the first identity authentication code and the second identity authentication code represent the identity of the atomizer from the power device 20 end and the atomizer 10 end respectively; when the first identity authentication code and the second identity authentication code are matched, the prestored first key and the prestored second key are matched, which indicates that the power device 20 and the atomizer 10 are matched; therefore, the identity authentication of the power device 20 and the atomizer 10 can be performed through the first identity authentication code and the second identity authentication code.
Preferably, the power device 20 and the atomizer 10 are determined to be matched when the prestored first key and the prestored second key are totally the same; meanwhile, the first identity authentication code and the second identity authentication code should be totally the same. Therefore, the step of the control unit 21 performing identity authentication according to the first identity authentication code and the second identity authentication code specifically includes:
the control unit 21 compares the first identity authentication code with the second identity authentication code; if the first identity authentication code and the second identity authentication code are consistent, the identity authentication is passed; the control unit 21 controls the power supply 22 to output a specified power to the heating element 12 to enable the heating element 12 to be heated, then the electronic cigarette is activated; if the first identity authentication code and the second identity authentication code are inconsistent, the identity authentication is not passed; the control unit 21 controls the power supply 22 to output a zero power to the heating element 12 to enable the heating element 12 not to be heated, then the electronic cigarette is prohibited to activate.
Further, the control unit 21 generates a first identity authentication code and acquires a second identity authentication code from the encryption authentication unit 11 when receiving an activation command, and then completes the identity authentication of the atomizer 10 and the power device 20. Herein, the activation command is a command generated when a user presses an ignition button of the electronic cigarette.
Of course, in some alternative embodiments, the control unit 21 can generate a first identity authentication code and acquire a second identity authentication code from the encryption authentication unit 11 when it is in communication connection with the encryption authentication unit 11, and then completes the identity authentication of the atomizer 10 and the power device 20.
Of course, in some other alternative embodiments, the control unit 21 can generate a first identity authentication code and acquire a second identity authentication code from the encryption authentication unit 11 according to a preset time interval, and then completes the identity authentication of the atomizer 10 and the power device 20.
Further, if the identity authentication is passed, when the control unit 21 controls the electronic cigarette to activate, the control unit 21 can acquire a number of times of smoking, a working duration of the atomizer and a working power of the atomizer, and calculate a tobacco liquid consumption according to the working duration of the atomizer and the working power of the atomizer; and then the control unit 21 updates the acquired prestored atomizer information, including the available number of puffs, the available smoking duration and the available amount of tobacco liquid, according to the acquired number of times of smoking, the acquired working duration of the atomizer and the calculated tobacco liquid consumption.
Further, after the control unit 21 updates the available number of puffs, the available smoking duration and the available amount of tobacco liquid, it sends the available number of puffs, the available smoking duration and the available amount of tobacco liquid that are updated to the encryption authentication unit 11 to store, so as to replace the available number of puffs, the available smoking duration and the available amount of tobacco liquid that are originally stored in the encryption authentication unit 11.
Further, each time the control unit 21 turns on the electronic cigarette or turns off the electronic cigarette, the control unit 21 acquires the available amount of tobacco liquid stored in the encryption authentication unit 11, and compares the acquired available amount of tobacco liquid with a preset threshold; when the available amount of tobacco liquid is less than the preset threshold, the control unit 21 controls the electronic cigarette to stop working, that is, the control unit 21 controls the power supply 22 to output a zero power to the heating element 12.
Of course, in some embodiments, a prompt device is arranged in the electronic cigarette, and the control unit 21 can control the prompt device to give a prompt when the available amount of tobacco liquid is less than the preset threshold. The prompt device may be a loudspeaker capable of making a prompt voice, also may be a buzzer capable of giving an alarm voice, and the like.
Further, in some embodiments, the control unit 21 can analyze the smoking habits of a user to generate a smoking report and a healthy smoking suggestion report, according to the number of times of smoking, the working duration of the atomizer, the working power of the atomizer, the tobacco liquid consumption, the tobacco liquid type and the like in each operation process, and sends the generated smoking report and healthy smoking suggestion report to a mobile terminal through establishing a communication connection with the mobile terminal, so that the user can better use the electronic cigarette. Thus, the user experience is improved.
The embodiment of the present disclosure provides an electronic cigarette, wherein an encryption authentication unit is arranged in an atomizer of the electronic cigarette and a control unit is arranged in a power device, and the encryption authentication unit is in communication connection with the control unit when the atomizer is connected to the power device, such that the control unit carries out the electronic cigarette control method to perform identity authentication for the atomizer and the power device, which effectively prevents the mixed use of the atomizer and the power device, improves the user experience and guarantees the merchants' interests.

Embodiment 2

Referring to FIG. 5, which is a flowchart of an electronic cigarette control method provided in an embodiment of the present disclosure; the electronic cigarette control method is applied to an electronic cigarette; the electronic cigarette is the electronic cigarette described in the above embodiments, and the method provided in the embodiment of the present disclosure is carried out by a control unit 21 in the electronic cigarette, to perform identity authentication for the atomizer and the power device. The control method for the electronic cigarette includes:

S100: generating a first identity authentication code.

The above first identity authentication code is an information validation code or MAC code generated and calculated at the power device end, which can represent the identity of the atomizer from the power device end.
Referring to FIG. 6, the above step of generating a first identity authentication code specifically includes:
S101: generating a random challenge data.
The above random challenge data is a random number generated for challenge in a challenge-response mechanism. The random challenge data generated each time is not fixed.
S102: acquiring prestored atomizer information from the encryption authentication unit.
The above prestored atomizer information is the basic information of the atomizer stored in the encryption authentication unit of the atomizer, including manufacturer information, version information, production information, a tobacco liquid type, etc.
S103: performing a calculation on the random challenge data, the prestored atomizer information and a prestored first key according to a prestored first encryption algorithm, to generate the first identity authentication code.
The above prestored first encryption algorithm is a SHA stored in the control unit of the power device. The prestored first encryption algorithm is a SHA-256.
The SHA-256 is used to perform a calculation on the random challenge data, the prestored atomizer information and the prestored first key to generate the first identity authentication code. Since the random challenge data is randomly generated, the first identity authentication code calculated each time is not a fixed value and varies depending on the random challenge data.
S120: acquiring a second identity authentication code from the encryption authentication unit.
The above second identity authentication code is an information validation code or MAC code generated and calculated at the atomizer end, which can represent the identity of the atomizer from the atomizer end.
Referring to FIG. 7, before S120, the control method for the electronic cigarette further includes:
S110: sending the random challenge data to the encryption authentication unit, so that the encryption authentication unit performs a calculation on the random challenge data, the prestored atomizer information and a prestored second key according to a prestored second encryption algorithm, to generate the second identity authentication code.
The above prestored atomizer information is the basic information of the atomizer stored in the encryption authentication unit of the atomizer, including manufacturer information, version information, production information, a tobacco liquid type, etc.
The above prestored second encryption algorithm is a SHA stored in the control unit of the power device. The prestored second encryption algorithm is a SHA-256.
The SHA-256 is used to perform a calculation on the random challenge data, the prestored atomizer information and the prestored second key to generate the second identity authentication code.
Since the random challenge data is of strong randomness, in order to guarantee that the match between the first identity authentication code and the second identity authentication code is related to the match between the first key and the second key, the random challenge data used to generate the first identity authentication code is sent to the encryption authentication unit, such that the encryption authentication unit calculates the second identity authentication code using the same random challenge data. Meanwhile, if the first identity authentication code is matched with the second identity authentication code, then the prestored first key is matched with the prestored second key, which means the power device is matched with the atomizer; therefore, the identity authentication of the power device 20 and the atomizer 10 can be performed through the first identity authentication code and the second identity authentication code.
In some embodiments, when an activation command is received, a first identity authentication code is generated and a second identity authentication code is acquired from the encryption authentication unit.
Of course, in some alternative embodiments, when the control unit and the encryption authentication unit are in communication connection, a first identity authentication code is generated and a second identity authentication code is acquired from the encryption authentication unit.
Of course, in some other alternative embodiments, a first identity authentication code is generated and a second identity authentication code is acquired from the encryption authentication unit according to a preset time interval.
S130: performing identity authentication according to the first identity authentication code and the second identity authentication code.
Referring to FIG. 8, the above step of performing identity authentication according to the first identity authentication code and the second identity authentication code specifically includes:

S131: comparing the first identity authentication code with the second identity authentication code.
S132: judging whether the first identity authentication code and the second identity authentication code are consistent.
S133a: if the first identity authentication code and the second identity authentication code are consistent, the identity authentication is passed.
S133b: if the first identity authentication code and the second identity authentication code are inconsistent, the identity authentication is not passed.

In the embodiment of the present disclosure, the power device and the atomizer are determined to be matched when the prestored first key and the prestored second key are totally the same; meanwhile, the first identity authentication code and the second identity authentication code are the same; therefore, when performing identity authentication according to the first identity authentication code and the second identity authentication code, it is needed to compare whether the first identity authentication code and the second identity authentication code are the same.
S140: judging whether the identity authentication is passed.
S150a: controlling the electronic cigarette to activate if the identity authentication is passed.
S150b: prohibiting the electronic cigarette to activate if the identity authentication is not passed.
It is judged whether the identity authentication is passed through judging whether the first identity authentication code and the second identity authentication code are consistent. If the first identity authentication code and the second identity authentication code are consistent, the identity authentication is passed, and the electronic cigarette is controlled to activate. If the first identity authentication code and the second identity authentication code are inconsistent, the identity authentication is not passed, and the electronic cigarette is prohibited to activate.
Further, referring to FIG. 9, in some embodiments, the control method for the electronic cigarette further includes:
S160: when the electronic cigarette is controlled to activate, acquiring a number of times of smoking, a working duration of the atomizer and a working power of the atomizer.
The above number of times of smoking refers to a number of puffs that the user takes during a process from the startup to the shutdown of the electronic cigarette, the number of times of smoking can be calculated through a change curve of air flow, each peak or trough is counted as one time.
